摘要： The present invention relates to X-ray imaging technology. In phase-contrast imaging, different types of image information, e.g. absorption image information and differential phase-contrast image information, may be obtained by a single image acquisition process. Individual types of image information comprise different image properties. The present invention relates to a frequency dependent combination of different types of image information to obtain a combined image having improved properties over the individual image information and their respective image information type. Accordingly, an apparatus (56) as well as a method (100) for image processing in X-ray imaging of an object is provided comprising receiving (102) first image information of the object of a first image information type, receiving (104) second image information of the object of a second image information type,wherein the second image information type is different from the first image information type. Subsequently the first image information and the second image information is combined(106)to obtain combined image information of the object, wherein the combination of the first image information and the second image information is a frequency-dependent combination, depending on the spatial frequency of the first image information and the second image information.

摘要： The invention relates to a detection apparatus comprising a filter (20) for filtering a conical radiation beam (4) such that at least a first region (22) and a second region (23) of the radiation beam are generated having different energy spectra, wherein the first region of the radiation beam illuminates a first detector area (25) on a detection surface (21) of a detector, thereby generating a first set of detection values, and the second region of the radiation beam illuminates a second detector area (26) on the detection surface, thereby generating a second set of detection values. For example, by using the filter the detection apparatus can be used as dual-energy computed tomography apparatus, wherein, for instance, a standard computed tomography apparatus can be transformed to a dual-energy computed tomography apparatus by adding the filter to the standard computed tomography apparatus, preferentially without modifying the radiation source and the detector.

摘要： The invention relates to an imaging apparatus (31) for imaging an object. A reconstruction unit (12) determines component projection data values, which correspond to, for example, a base material of the object, and reconstructs an image of the object based on the determined component projection data values. A component projection data value, which corresponds to a ray, is determined as a combination of weighted base functions, which depend on energy projection data values of the same ray and the orientation of the same ray. This allows considering a possible dependency of the corresponding decomposition on the orientation of the ray, thereby allowing the imaging apparatus to improve the quality of decomposing the provided energy projection data values into the component projection data values and thus of a finally reconstructed image of the object, which is reconstructed based on the component projection data values.

摘要： A method for providing a displayable pixel data set (11) from measurement data (3) provided by a differential phase-contrast X-ray imaging system (1) and a device (7) adapted to perform such method are proposed. The measurement data (3) comprise three types of measurement information: an absorption representing image data set A, a differential phase-contrast representing image data set D and a coherence representing image data set C. Each of the image data sets A, D and C comprises a 2-dimensional or 3-dimensional set of pixels (5) and the three image data sets are spatially aligned with each other. In the method for providing a displayable pixel data set, a colour value corresponding to a position in a 3- dimensional colour space (9) is attributed to each pixel (13) in the displayable pixel data set (11), wherein each of three coordinates HSI of the position in the 3-dimensional colour space (9) is determined based on data values A ij , D ij , C ij of a corresponding pixel (5) in a respective one of the image data sets A, D, C. For example, the coordinates within the colour space (9) may be indicated by an intensity I, a saturation S and a hue H thereby allowing a very intuitive representation of the complex DPCI measurement data to a human observer.
